Abstract

L'invention concerne un fil-guide présentant à sa surface un revêtement glissant et tenace constitué d'une matière particulaire glissante finement divisée. Le revêtement selon l'invention présente une épaisseur d'au plus environ 0,00002 pouce, un coefficient de frottement d'au plus environ 0,030 et une dureté d'au moins 1,0 Mohs. De préférence, le revêtement de surface comprend une couche monomoléculaire de disulfure de tungstène. Le fil-guide selon l'invention comporte une configuration à pointe distale améliorée constituée d'un élément central allongé et souple à au moins une section conique à son extrémité distale et une partie distale aplatie. La partie distale présente au moins deux régions aplaties à section décroissante dans le sens distal. Une bobine hélicoïdale souple est fixée à l'élément central et comprend au moins trois régions distinctes espacées de manière croissante dans le sens distal. De préférence, la totalité de la longueur du fil-guide à proximité de la bobine hélicoïdale présente le revêtement de surface glissant selon l'invention.
